About this landmark
Hilltop vistas and access trails
Double Peak Park is located at 900 Double Peak Drive in San Marcos, with the summit elevation at 1,646 feet (502 meters). The peak rises approximately 1,000 feet above its north base, offering topographic prominence of 464 feet. The summit area is wheelchair accessible and offers panoramic views on clear days stretching to Mexico, downtown San Diego, San Clemente Island, Catalina Island, the Palos Verdes Peninsula, the Santa Ana Mountains, and the San Bernardino Mountains. These far-reaching vistas make the summit a destination for hikers and visitors seeking expansive scenery across Southern California. The park is owned and operated by the City of San Marcos Parks & Recreation Department.
Geologic history and wildfire resilience
The bedrock at Double Peak consists of Santiago Peak volcanics, formations from the Late Jurassic to Early Cretaceous period, roughly 160 to 120 million years old. These ancient formations are interpreted as remnants of a volcanic island-arc system that existed during the Mesozoic Era, creating the geologic foundation visible today. A historic olive tree at the site survived the 2014 Cocos Fire, which started in the hills near Double Peak. A monument stands at the summit, commemorating the location's significance in the region's history and geography.
The 2014 Cocos Fire, which ignited on May 14, 2014, burned 1,995 acres and destroyed 40 buildings in the surrounding area, demonstrating the wildfire risk present in this region. The fire reached 100 percent containment on May 22, 2014. The park's survival and continued operation demonstrate its resilience in a region subject to periodic wildfire risk and the importance of preparedness in coastal chaparral areas.
Access and amenities
Access to the summit can be approached from the north side through Discovery Lake Park, where the trailhead is closed to motorized vehicles and the distance to the summit is 2.5 miles. The east-side trail features steep terrain with rugged staircase-like rock and loosely packed shale, challenging hikers with unstable footing. Most trails to the summit are classified as moderately strenuous. Vehicle access from the south is via Double Peak Drive from the San Elijo Hills neighborhood. Standard driving directions involve Highway 78 to Twin Oaks Valley Road, then south to Double Peak Drive.
The park provides amenities including an amphitheater, shelter, picnic tables, play equipment, a kiosk, permanent restrooms, a telescope, and trail connections to neighboring parks. Visitors can reserve the shelter and amphitheater through the city's parks reservation system. For information and reservations, contact the Parks & Recreation Department at (760) 744-9000 ext. 3500.
Insurance connection: Wildfire and rebuilding

Standard homeowners policies may exclude building code upgrade coverage, creating significant gaps when fires require rebuilding to current codes. Many wildfire victims have been underinsured when dwelling coverage limits were based on market value rather than actual rebuild costs. The residential insurance guide notes insurers cannot cancel policies during rebuilds after total losses from declared disasters, except for fraud or misrepresentation. Eligibility and limits depend on individual policies. The issued policy controls.
